I did this with a manual 35mm camera. You can purchase rolls of infrared sensitive film. You must make a focus adjustment when shooting infra red. Most manual camera focus rings have a second focus index mark, since infrared light focus converges slightly differently than natural light. See:
Alfred Wegener as the initial author on the theory of plate tectonics comes to mind. He was a trained meteorologist who observed the similarities between geological formations between the South American east coast and African west coast. He was lucky, in that his father in-law was a prominent geologist and helped him defend this thesis.
Pretty good if they did it in a day. Encountered the same issue and it took me at least three days to resolve. The issue presented itself as a database table not updating.
